STANDARD THERMODYNAMIC PROPERTIES OF CHEMICAL SUBSTANCES
This table gives the standard state chemical thermodynamic properties of about 2400 individual substances in the crystalline, liquid, and gaseous
states. Substances are listed by molecular formula in a modified Hill order; all compounds not containing carbon appear first, followed by those that
contain carbon. The properties tabulated are:
∆
f
H° Standard molar enthalpy (heat) of formation at 298.15 K in kJ/mol
∆
f
G° Standard molar Gibbs energy of formation at 298.15 K in kJ/mol
S° Standard molar entropy at 298.15 K in J/mol K
C
p
Molar heat capacity at constant pressure at 298.15 K in J/mol K
The standard state pressure is 100 kPa (1 bar). The standard states are defined for different phases by:
• The standard state of a pure gaseous substance is that of the substance as a (hypothetical) ideal gas at the standard state pressure.
• The standard state of a pure liquid substance is that of the liquid under the standard state pressure.
• The standard state of a pure crystalline substance is that of the crystalline substance under the standard state pressure.
An entry of 0.0 for ∆
f
H° for an element indicates the reference state of that element. See References 1 and 2 for further information on reference
states. A blank means no value is available.
We are indebted to M.V. Korobov for providing data on fullerene compounds.
